Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

The humidifying nozzle assembly 10 of the air treatment device 1 and the air treatment device 1 according to the embodiment of the present invention are described below with reference to the accompanying drawings. Specifically, the air treatment device 1 may be an air conditioner. More specifically, the air treatment device 1 may be an air conditioning indoor unit, such as an air duct machine, a ceiling machine, or the like.

As shown in fig. 1 to 8, the humidifying nozzle assembly 10 of the air treatment device 1 according to the embodiment of the present invention includes a silencer tube 101 and a gas nozzle 102, the silencer tube 101 includes a steam inlet a and a steam outlet b, the steam inlet a is adapted to be connected to a steam source, the gas nozzle 102 is connected to the steam outlet b, and a gas nozzle e is provided on an outer peripheral wall of the gas nozzle 102. Thus, steam from the steam source may enter the silencer duct 101 through the steam inlet a and further flow to the air lance 102 through the steam outlet b, and the steam in the air lance 102 may be discharged through the air lance holes e, thereby being used to regulate the humidity of the air in the chamber when the humidifying lance assembly 10 is used on the air treatment device 1.

In the related art, when steam flows in a pipeline, condensate water is inevitably generated, when gas and liquid are mixed and flow in the pipeline, the pipeline frequently generates sounds of boiling water or blowing bubbles, the noise is high, the pipeline also vibrates, the steam conveying process is unstable, and the quality of products and customer experience are seriously influenced.

According to the humidifying nozzle assembly 10 of the air treatment device 1, the silencing pipe 101 is arranged, so that noise is reduced, vibration of a pipeline is weakened to a certain extent, stable conveying of steam is guaranteed, and product quality and user experience are improved.

In some embodiments of the present invention, the steam outlet b is located at one axial end of the silencer duct 101, one axial end of the gas lance 102 is connected to the steam outlet b, and the other end of the gas lance 102 is closed. Specifically, for example, as shown in fig. 1 to 8, one axial end of the silencer duct 101 has a steam outlet b, the other axial end of the silencer duct 101 has a steam inlet a, one axial end of the gas lance 102 is connected to the steam outlet b, the other axial end of the gas lance 102 (i.e., the end remote from the silencer duct 101) is closed, and the outer peripheral wall of the gas lance 102 is provided with gas injection holes e. In this way, the steam can enter the silencer 101 through the steam inlet a, the noise of the steam and condensed water flowing is greatly reduced under the silencing effect of the silencer 101, then the steam and condensed water flow to the air spraying pipe 102 through the steam outlet b, and the steam can be sprayed into the indoor environment where the air treatment device 1 is located through the air spraying holes e for humidifying the indoor. Therefore, the structure is simple, and the other axial end of the air spraying pipe 102 is closed, so that the steam in the air spraying pipe 102 is favorably ensured to be sprayed out from the air spraying holes e, the spraying speed of the steam is improved, the spraying range is further enlarged, and the humidifying efficiency for the indoor environment is favorably improved.

In some further embodiments of the present invention, as shown in fig. 3 and 8, the steam outlet b is located at the lowest position of the axial end of the silencer duct 101, thereby facilitating smooth drainage of condensed water in the silencer duct 101 from the steam outlet b, and avoiding influence on the silencing effect due to accumulated condensed water in the silencer duct 101.

In some embodiments of the present invention, the silencer duct 101 extends obliquely upward in the direction from the gas lance 102 to the silencer duct 101. Specifically, for example, as shown in fig. 8, the steam outlet b is located at the lowest position of one axial end of the silencer duct 101, and the silencer duct 101 extends obliquely upward in the direction from the gas lance 102 to the silencer duct 101. Thereby, the condensed water in the silencer pipe 101 is smoothly discharged to the air jet pipe 102 from the steam outlet b, the gas-liquid round condition is reduced, and the influence on the silencing effect due to the accumulated condensed water in the silencer pipe 101 is avoided.

Specifically, as shown in fig. 8, the included angle α between the central axis of the gas lance 102 and the central axis of the muffler pipe 101 is α, which satisfies: alpha is more than or equal to 2 degrees and less than or equal to 15 degrees. For example, α is 2.5°、3°、3.6°、4°、4.3°、4.9°、5.1°、5.8°、6.3°、7.6°、8.2°、8.9°、9.2°、9.9°、10.1°、10°、10.85°、11°、11.3°、11.6°、11.9°、12°、12.4°、12.6°、13.2°、13.8°、14.5°、14.9° or 13 ° or other parameters. Experiments of the inventor prove that the alpha is more than or equal to 2 degrees and less than or equal to 15 degrees, so that the condensed water discharging effect in the silencer pipe 101 is improved, the problem that the whole silencer pipe 101 and the air jet pipe 102 occupy a large space in the width direction due to the fact that the alpha is large is avoided, and meanwhile, the processing difficulty and the manufacturing cost are reduced.

Of course, the present invention is not limited thereto, and in alternative embodiments, the silencer duct 101 may be non-inclined, i.e., the central axis of the silencer duct 101 is disposed parallel to the central axis of the gas lance 102. For example, as shown in fig. 3, the central axis of the silencer duct 101 is parallel to the central axis of the gas lance 102, and both are parallel to the horizontal plane. This is advantageous in that it is possible to simplify the structure, reduce the processing and manufacturing costs, and ensure that the steam smoothly enters the gas injection pipe 102 from the silencer pipe 101, and reduce abnormal sounds generated in the flow process of the steam from the silencer pipe 101 to the gas injection pipe 102.

In some embodiments of the present invention, as shown in FIG. 8, the inner diameter of the silencer duct 101 is A and the inner diameters of the gas lances 102 are C, with A and C satisfying: a > C. For example, a=1.2c; a=1.5c; a=1.9c; a=2.1c; a=2.5c; a=2.9c; a=3c; a=4c; or a=5c, etc. Therefore, the noise is further reduced, the vibration of the pipeline is weakened, the stable conveying of steam is further ensured, and the product quality and the user experience are improved.

In some alternative embodiments of the present invention, as shown in FIGS. 1-3 and 8, the steam outlets b are connected to the gas lance 102 by outlet pipes 103. This is advantageous not only in terms of a simple structure, but also in terms of a large number of pipelines, which are adapted to the different configurations of the air treatment device 1.

Specifically, as shown in fig. 1 to 8, the central axis of the outlet pipe 103 is disposed in parallel with the central axis of the muffler pipe 101. Thereby, it is advantageous to ensure that the steam in the silencer duct 101 smoothly flows to the gas lance 102 through the outlet duct 103, and to simplify the connection between the pipes, facilitating the manufacturing.

Specifically, the inner diameter of the outlet tube 103 is B, and the inner diameters of the gas lance 102 are C, B and C satisfying: c > B. For example, c=1.3b, c=1.85; c=1.99b; c=2.2b; c=2.86B; c=3.3b; c=4b; c=4.5b; c=5b. Therefore, the pipe diameter of the outlet pipe 103 is smaller than that of the air injection pipe 102, so that the flow rate of the gas entering the air injection pipe 102 from the steam is increased, the steam can flow in the air injection pipe 102 conveniently, and the steam can be discharged from the air injection holes e smoothly.

Alternatively, the outlet pipe 103 may be welded to the silencer pipe 101, whereby the connection process is simple, which is advantageous in improving the production efficiency.

In some further embodiments of the present invention, as shown with reference to fig. 1-3 and 8, the outlet pipe 103 and the gas lance 102 are connected by a flared pipe 106, and the area of the flared pipe 106 that flows past gradually increases in the direction from the silencer pipe 101 to the gas lance 102. Thereby, it is advantageous to achieve smoothness of connection between the outlet pipe 103 and the gas lance 102, thereby ensuring smoothness of steam flow.

Optionally, the central axis of the flared tube 106 is collinear with the central axis of the gas lance 102. Thus, the method is beneficial to simplifying processing and reducing processing and manufacturing cost. Specifically, the flared tube 106 and the gas lance 102 are integrally formed, thereby facilitating not only simplification of the production process and reduction of the production cost, but also improvement of the connection strength between the flared tube 106 and the gas lance 102.

Specifically, as shown in fig. 1-3 and 8, the flared tube 106 may be sleeved on an end of the outlet tube 103 away from the silencer tube 101, for example, the flared tube 106 is in interference fit with the outlet tube 103, so as to achieve connection between the flared tube 106 and the outlet tube 103.

In some alternative embodiments of the present invention, as shown in fig. 1-8, the humidifying nozzle assembly 10 further includes an air inlet pipe 104, the air inlet pipe 104 being connected to the steam inlet a. Specifically, one end of the intake pipe 104 may be inserted into the muffler pipe 101 through the steam inlet a, and the other end of the intake pipe 104 is adapted to be connected to a steam source, thereby not only being simple in structure, but also facilitating the growth of a pipe to match with different air treatment apparatuses 1.

Optionally, the central axis of the air inlet pipe is disposed parallel to the central axis of the air lance 102. Therefore, the structure is simplified, and the processing cost is reduced.

In some alternative embodiments of the invention, referring to FIG. 8, the outlet tube 103 has an inner diameter B and the inlet tube has an inner diameter D, B and D satisfying: d=0.8 to 1.2B. For example, d=0.8b, d=0.85B, d=0.89B, d=0.91B, d=0.99B, d=1.05B, d=1.09B, d=1.11B, d=1.2B, d=1.16B, d=1.19B, or the like. From this, be favorable to further guaranteeing the stability that steam circulated at humidification spray tube subassembly 10, further weaken the vibration of pipeline, the noise reduction improves product quality and user's experience.

In some embodiments of the present invention, the other end of the intake pipe, i.e., the end remote from the muffler pipe 101, is provided with a pipe joint. Thereby facilitating the connection of the air inlet pipe with other pipelines through the pipe joint, for example, the pipe joint arranged on the air inlet pipe is connected with one end of the pipeline, and the other end of the pipeline is connected with the steam source. Therefore, the structure is simple, and the welding problem between pipelines is avoided.

According to some embodiments of the present invention, the outlet tube 103 has an inner diameter B and the gas injection holes e have a diameter H, H and B satisfying: h is less than B. For example, h=0.3b, h=0.36b, h=0.45B, h=0.5B, h=0.55B, h=0.56B, h=0.6b, h=0.7b, h=0.75B, h=0.8b, h=0.9B, thereby contributing to not only ensuring smooth ejection of steam from the ejection holes e but also ensuring the discharge speed of steam.

In some alternative embodiments of the present invention, the inner diameter of the gas lance 102 is C and the inner diameters of the steam outlets b are E, C and E satisfying: c > E. For example, c=1.2e, c=1.3e, c=1.4e, c=1.7e, c=2.2e, c=2.8e, c=3e, c=3.5e, c=4e, c=4.5e, c=5e, or c=5.5e. This is advantageous in ensuring that the steam in the silencer duct 101 is smoothly discharged from the steam outlet b into the gas lance 102.

Alternatively, the gas lance 102 may be connected to the muffler pipe 101 without the above-described flare pipe 106 and outlet pipe 103, and the gas lance 102 is directly connected to the muffler pipe 101 as shown with reference to fig. 4 to 7. For example, an end face of the gas lance 102 adjacent to one end of the silencer duct 101 may be welded to the silencer duct 101, and an end face of the gas lance 102 adjacent to one end of the silencer duct 101 surrounds the steam outlet b. Therefore, the arrangement of the middle pipeline is avoided, the material is saved, and the material cost and the processing cost are reduced.

In some embodiments of the present invention, the gas injection holes e are a plurality of, and the plurality of gas injection holes e are disposed at intervals along the axial direction of the gas injection tube 102. Thus, the air injection range of the air injection pipe 102 is advantageously increased, the air injection efficiency is improved, and the humidifying effect is further improved. Of course, the invention is not limited thereto, and in alternative embodiments, one gas injection hole e is an elongated slot and one gas injection hole e extends in the axial direction of the gas injection tube 102.

Specifically, the plurality of gas injection holes e are uniformly spaced apart in the axial direction of the gas injection tube 102. Therefore, the structure is simple, and the processing and manufacturing cost is reduced.

In some alternative embodiments of the present invention, the plurality of gas injection holes e may be divided into a plurality of groups of holes, the groups of holes being disposed at intervals in the circumferential direction of the gas injection tube 102, the plurality of gas injection holes e of each group of holes being arranged at intervals in the axial direction of the gas injection tube 102. Thereby, the air injection range of the air injection pipe 102 is further increased, the air injection efficiency is improved, and the humidifying effect is further improved.

Alternatively, the spacing between adjacent gas injection holes e is different among the plurality of gas injection holes e of each group of holes, and the spacing between adjacent gas injection holes e gradually increases in the direction from the silencer duct 101 to the gas injection duct 102, that is, the closer to the silencer duct 101, the closer to the gas injection holes e, and the more sparse to the gas injection holes e. Therefore, the steam is discharged from a plurality of different air injection holes e, and the uniformity of the steam discharged from each air injection hole e is guaranteed.

Alternatively, the cross-sectional area of the silencer duct 101 remains unchanged. Therefore, the silencer duct 101 has a simple structure and is convenient to manufacture.

The air treatment device 1 according to the embodiment of the present invention includes the housing 11 and the humidifying nozzle assembly 10 in the above embodiment.

According to the air treatment device 1 provided by the embodiment of the invention, the humidification spray pipe assembly 10 is beneficial to reducing noise, weakening vibration of a pipeline to a certain extent, facilitating stable conveying of steam and improving product quality and user experience.

Specifically, as shown in fig. 9-11, the air treatment device 1 includes a housing 11 and a humidifying nozzle assembly 10, wherein an air inlet (not shown) and an air outlet 111 are provided on the housing 11, the humidifying nozzle assembly 10 is located in the housing 11, and the air jet pipe 102 is located between the air inlet and the air outlet.

More specifically, the air treatment device 1 further includes a heat exchanger 12, the heat exchanger 12 being provided within the housing 11, and the air lance 102 being located between the heat exchanger 12 and the air outlet 111. It can be appreciated that the air lance 102 is disposed between the heat exchanger 12 and the air outlet 111, so that the mixing time of the water vapor and the air flow in the air treatment device 1 can be prolonged, the water vapor can be fully mixed with the air flow, the difficulty in connection and assembly of the air lance 102 can be reduced, and meanwhile, the difficulty in maintenance of the air lance 102 can be reduced.

Specifically, as shown in fig. 11, the air treatment device 1 further includes a wind wheel 13. Wherein, humidification spray tube subassembly 10, heat exchanger 12 and wind wheel 13 are all installed in shell 11 and are located between the air intake and the air outlet of shell 11, and jet-propelled pipe 102 is located between heat exchanger 12 and wind wheel 13, and when wind wheel 13 work, the air current enters into shell 11 from the air intake and carries out heat transfer with heat exchanger 12, and the air current after the heat transfer mixes with the steam that spouts from jet-propelled pipe 102 and further flows through wind wheel 13 to air outlet 111 to when realizing adjusting indoor ambient temperature, the air humidity in the regulation room.

Optionally, a drain hole (not shown) is provided at the lowest position of the air lance 102, a deflector 108 is provided on the peripheral wall of the air lance 102, one end of the deflector 108 is disposed adjacent to the drain hole, and the other end of the deflector 108 extends to the heat exchanger 12 of the air treatment device 1 to guide the condensed water in the air lance 102 to the heat exchanger 12.

The steam generating device 2 according to the embodiment of the present invention is described below.

As shown in fig. 12 and 13, according to the steam generating device 2 of the embodiment of the present invention, the steam generating device 2 is adapted to generate steam for supplying steam to the air treatment device 1, and the steam generating device 2 includes: the casing 25, the tank assembly 21, the float valve 22, the heating assembly 23, and the communication pipe 26.

In particular, the enclosure 25 is adapted for ceiling mounting. For example, the enclosure 25 may be suspended from a ceiling or from a wall. Therefore, the space occupied by the shell 25 can be reduced, and meanwhile, the difficulty in mounting the shell 25 can be reduced, so that the mounting efficiency of the shell 25 can be improved.

As shown in fig. 12 and 13, the water tank assembly 21 is provided in the cabinet 25, the water tank assembly 21 has a steam port 2111 and a water inlet 2121 for supplying water to the inside of the water tank assembly 21, the water inlet 2121 communicates with a water source, and water vapor in the water tank assembly 21 flows to the steam inlet a through the steam port 2111 under the driving of air pressure.

It will be appreciated that the water tank assembly 21 may be operated to generate water vapor, and as the volume of the generated water vapor increases, the pressure of the water vapor in the water tank assembly 21 may also increase, and when the water vapor pressure in the water tank assembly 21 is greater than the pressure at the steam port 2111, the water vapor in the water tank assembly 21 may flow through the steam port 2111 to the steam inlet a and be delivered to the indoor space through the air injection pipe 102. Therefore, the pressure of the water vapor can be utilized to drive the water vapor to flow, so that a fan for driving the water vapor to flow from the water tank assembly 21 to the vapor inlet a is omitted, the working noise of the air treatment device 1 can be reduced, and the use comfort of a user is improved.

As shown in fig. 12, a ball float valve 22 is provided in the tank assembly 21 to control the on-off of the water inlet 2121. Therefore, by arranging the ball float valve 22, the water tank assembly 21 and a water source can be connected in time under the condition that the water tank assembly 21 lacks water, and the water tank assembly 21 and the water source can be disconnected in time under the condition that the water tank assembly 21 does not lack water. Specifically, when the liquid level in the tank assembly 21 is lower than a preset level, the float valve 22 may control the water source to communicate with the tank assembly 21, whereby water may be replenished into the tank assembly 21; when the liquid level in the water tank assembly 21 reaches a preset level, the float valve 22 controls the water source to be disconnected from the water tank assembly 21.

As shown in fig. 12 and 13, the heating assembly 23 is provided inside the water tank assembly 21. It will be appreciated that the heating assembly 23 heats the water in the water tank assembly 21, the water evaporates at high temperature to generate water vapor, and when the water vapor collected in the water tank assembly 21 is stronger than the pressure at the vapor port 2111, the water vapor in the water tank assembly 21 can be transported to the air treatment device 1 through the vapor port 2111 under the action of the vapor pressure and is transported to the indoor space through the air treatment device 1.

Specifically, the heating element 23 may be a PTC (Positive Temperature Coefficient, thermistor). The PTC is a semiconductor resistor typically having temperature sensitivity, and by providing the PTC, the heating power of the heating assembly 23 can be ensured, and the generation rate of steam can be further increased, thereby reducing the response time of the steam generating device 2. In addition, the PTC has very high safety as compared with other types of heating elements 23, and is not liable to cause ignition or the like even when dry-burned.

One end of the communication pipe 26 communicates with the vapor inlet 2111, the other end of the communication pipe 26 communicates with the vapor inlet a (or the valve joint 105 described above), and the vapor generated by heating the heating unit 23 is adapted to flow to the humidifying nozzle assembly 10 after passing through the vapor inlet 2111 and the communication pipe 26 in this order.

It will be appreciated that when the steam generator 2 is operated, the water in the water tank assembly 21 may be evaporated to generate steam under the heating of the heating assembly 23, and as the volume of the generated steam increases, when the pressure of the steam in the water tank assembly 21 is greater than the pressure at the steam port 2111, the high pressure steam in the water tank assembly 21 may sequentially pass through the steam port 2111, the communication pipe 26 and the humidifying nozzle assembly 10, be sprayed out through the air spraying holes e of the air spraying pipe 102, then be mixed with the air flow in the air treatment device 1, and finally be delivered to the indoor space.

In some embodiments of the invention, as shown in fig. 12, the tank assembly 21 has a drain outlet 2112. It will be appreciated that during long-term operation of the steam generator 2, the water within the tank assembly 21 is heated by the heating assembly 23 for a long period of time to evaporate into steam. Because the steam is difficult to carry away impurities such as chloride ions and calcium ions in the water, the concentration of the impurities is higher and higher after long-term accumulation, so that the water tank assembly 21 can be corroded, other detection elements in the water tank assembly 21 can be corroded, and the operation reliability of the steam generating device 2 is affected. Impurities carried in the water are liable to scale in the tank assembly 21, and the thicker the scale layer is, the more difficult it is to clean. In addition, the water tank assembly 21 is inevitably wrapped with water mist carrying impurities when the steam is discharged, and when the impurity content in the water is too high, the sprayed water mist can also influence the health of people. Accordingly, the water tank assembly 21 needs to be cleaned periodically, and the water drain 2112 is provided, so that the cleaned sewage can be discharged out of the water tank assembly 21 through the water drain 2112, and the cleanliness of the water tank assembly 21 can be reduced.

In addition, when the water tank assembly 21 needs to be overhauled or an emergency occurs, and water in the water tank assembly 21 needs to be discharged, the water in the water tank assembly 21 can be discharged through the water outlet 2112. Specifically, the drain port 2112 is provided at the bottom of the tank assembly 21, the drain port 2112 may be connected to a sink or bathroom equipment through a drain pipe, water drained from the tank assembly 21 may automatically flow into the sink or urinal by gravity, and a drain valve is provided at the drain port 2112.

In some embodiments of the present invention, the water tank assembly 21 includes a water replenishing tank 212 and a working water tank 211, one end of the water replenishing tank 212 is communicated with a water source, the other end of the water replenishing tank 212 is communicated with the working water tank 211 through a pipeline, the heating assembly 23 is arranged in the working water tank 211 for heating water in the working water tank 211, and the steam port 2111 is arranged on the working water tank 211. The water replenishing tank 212 can be used for timely delivering water replenishing to the working water tank 211, and the problem that the working water tank 211 cannot be replenished with water due to temporary water stoppage can be avoided by arranging the water replenishing tank 212, so that when water stoppage occurs for a short time, the water replenishing tank 212 can still timely replenish water to the working water tank 211, and the working water tank 211 can still continue to work at the moment, so that the reliability and safety of the work of the steam generating device 2 can be improved.

For example, in some examples of the present invention, the water replenishment tank 212 is provided with one, the working tank 211 is provided with a plurality, and the plurality of working tanks 211 are respectively communicated with the water replenishment tank 212 through pipes.

As another example, in some examples of the present invention, the water replenishment tank 212 is provided in plurality, the working tank 211 is provided in plurality, and the plurality of water replenishment tanks 212 are fitted in one-to-one correspondence with the plurality of working tanks 211.

Further, a check valve 24 is provided in the line between the refill tank 212 and the working tank 211 so that fluid can only flow from the refill tank 212 to the working tank 211. Therefore, water in the working water tank 211 can be prevented from flowing back into the water replenishing water tank 212 under the action of high-pressure steam, and meanwhile, steam in the working water tank 211 can be prevented from flowing back into the water replenishing water tank 212, so that the singleness of the flowing direction of the steam in the working water tank 211 can be ensured. It should be noted that, the check valve 24 herein can only enable fluid to flow from the water replenishment tank 212 to the working tank 211, and at the same time can avoid the backflow of steam in the working tank 211 into the water replenishment tank 212.

In order to ensure the safety of the operation of the steam generator 2, it may be configured that the water replenishment tank 212 is capable of supplying water to the operation tank 211 when no steam is generated in the operation tank 211. Or when the air pressure in the working water tank 211 is the same as the air pressure in the water replenishment water tank 212, the water replenishment water tank 212 delivers the replenishing water to the working water tank 211.
